Question : Comprehension:
Read the given passage and answer the questions that follow.
On May 2, 2018, severe dust storms and thunderstorms hit parts of Rajasthan, Uttar Pradesh, and other adjoining regions. Explaining the reasons behind such a severe weather system, M. Mohapatra, a senior scientist with the India Meteorological Department (IMD), said that dust storms and thunderstorms are a result of nearly similar weather conditions, like intense heat. Areas that have moisture in the air experience thunderstorms, while those which don't have moisture experience dust storms. "All such conditions were being fulfilled on that day. The region had moist easterly winds coming from the Bay of Bengal, and there was a western disturbance system too. All this together triggered the events on May 2," he added.
In simple terms, a dust storm can be explained as a phenomenon when strong winds carry dust over an extensive area.
As far as the timing of their occurrence is concerned, Mohapatra stated that there is no deviation in the time of occurrence of a dust storm or thunderstorm activity, as they usually peak in the pre-monsoon period.
These events happen between March and May only. In the pre-monsoon period, temperatures are very high, around 44–45 degrees Celsius, which leads to such activities.
Even though dust storms and thunderstorms are a common feature every year, there has been no focused work on studying the trends related to them. "In the coming years, there could be more instances of intense thunderstorms and sand storms, but they have to be studied in detail, looking at the data from over 30-40 years to notice a trend. Work has been more or less confined to cyclones and monsoon systems, but not much on dust storms or thunderstorms. It needs study," admitted Mohapatra.
The extent of damage caused by thunderstorm activity in India can be gauged from the data of India's National Crime Records Bureau (NCRB). As per the NCRB data, compared to other natural disasters like cyclones, floods, or heat waves, lightning kills more people in India. For instance, at least 25 per cent of the 10,510 accidental deaths attributable to forces of nature in 2015 were due to lightning. The number of deaths due to lightning has constantly remained over 2,000 every year since 2005.
Question:
Which of the following statements is NOT true according to the passage?
Option 1: The western disturbances cause dust storms in Rajasthan and nearby regions.
Option 2: Both, dust storms and thunderstorms occur due to similar weather conditions like intense heat.
Option 3: Thunderstorms occur where the air is dry.
Option 4: Cyclones and monsoon systems have been studied more than dust storms and thunderstorms.
Correct Answer: Thunderstorms occur where the air is dry.
Solution : The third option is correct.
The passage clearly states that areas with moisture in the air experience thunderstorms, while those without moisture experience dust storms. Therefore, thunderstorms are associated with moist conditions, and the statement implying thunderstorms occur where
Question : Select the INCORRECTLY spelt word.
Option 1: Gllidder
Option 2: Airplane
Option 3: Helicopter
Option 4: Ladybug
Correct Answer: Gllidder
The incorrect spelling gllidder contains the extra letters "l" and "d". The correct spelling is "glider". A glider typically refers to an unpowered aircraft that is designed to fly for long distances using upward air currents and
Question : If the 7-digit number $x$468$y$05 is divisible by 11, then what is the value of ($x$ + $y$)?
Option 1: 12
Option 2: 14
Option 3: 8
Option 4: 10
Correct Answer: 12
Solution : Given: If the 7-digit number $x468y05$ is divisible by 11. Then, Sum of the digits at odd places – Sum of the digits at even places = 0 or, 11 Now, Sum of the digits at odd places – Sum of the digits at even
Question : Study the given graph and answer the question that follows. The graph shows data related to the number of students enrolled for a vocational course in two institutes (X and Y) during three years. What is the difference between the average number of students enrolled in Institute X in 2010 and 2011 and that in Institute Y in 2011 and 2012?
Option 1: 20
Option 2: 15
Option 3: 18
Option 4: 22
Correct Answer: 20
Solution : Students enrolled in institute X in 2010 and 2011 = 320 + 240 = 560 Average = $\frac{\text{Sum of all the observations}}{{\text{Total number of observations}}}=\frac{560}{2} = 280$ Students enrolled in Institute Y in 2011 and 2012 = 320 + 200 = 520 Average = $\frac{520}{2}=
Question : Aarush and Maahi together can do a piece of work in 10 days. If Aarush alone can do the same work in 15 days, then how many days Maahi alone will take to do the same work?
Option 1: 25
Option 3: 30
Option 4: 20
Correct Answer: 30
Solution : Let us assume the total unit of work to be 30, which is the LCM of 15 and 10. Efficiency of Aarush and Maahi = $\frac{30}{10}$ = 3 units/day Efficiency of Aarush = $\frac{30}{15}$ = 2 units/day Efficiency of Maahi = 3 – 2 =
Question : Directions: If 27 * 4 = 77 and 31 * 9 = 239, then 21 * 6 = ?
Option 1: 94
Option 2: 107
Option 3: 99
Option 4: 106
Correct Answer: 99
Solution : Given: 27 * 4 = 77 and 31 * 9 = 239
Like, 27 * 4 = 77→27 × 4 = 108; 27 + 4 = 31; 108 – 31 = 77 And, 31 * 9 = 239→31 × 9 = 279; 31 + 9
